Its frustrating isnt it! Claire was the same. She would usually take the food into her mouth then push it out with her tongue, or just not open her mouth at all. We ended up taking a couple of breaks for a few days, then goin back to it. She didnt really start eating solids until about 8 - 9 months, but we did have some success after giving it a break.

I talked with the nurse about it and she told me the tongue thing is a reflex, because they use their tongue to get the milk out of the breast and it sometimes takes them a bit of time to learn how to swallow without moving their tongue.
